Product Description:
Cellulose Acetate Phthalate is widely used in the pharmaceutical industry as an enteric coating material for tablets and capsules. Its primary application lies in its ability to resist dissolution in the acidic environment of the stomach, ensuring that the drug is released only in the more alkaline conditions of the intestines. This property makes it particularly useful for protecting drugs that are sensitive to stomach acid or for delivering medications that need to act locally in the intestines. Additionally, it is employed in the production of controlled-release formulations, where it helps in achieving a delayed or sustained release of the active pharmaceutical ingredient. Beyond pharmaceuticals, it is also utilized in the food industry as a coating agent for certain food products to enhance stability and control moisture absorption.
